ROOF GONSTRUGTION.

Application filed Octbber 16, 1926, Seiial No. 141,918. Renewed December 3, 1928.

This invention relates to corrugated roofs. The general object of m invention is to construct a roof wherein fi rous material is used to produce a finished roof which simulates one shingled with tile.

Another object is to construct a corrugated composition shingle roof which, while weather proof and strong is cheap to construct owing to the fact that short lengths of lum- I her may be used.

Other objects of my invention will be ap parent from the following description taken in connection with the accompanying drawings wherein:

Fig. 1 is a partial view of a'house roof showing my invention;

Fig. 2 is a section of a roof showing the method of construction;

Fig. 3 is a section taken on line 3-3 of Fig. 2;

Fig. 4 is a top, plan view showing the progressive steps employed in the construction of my roof;

Fig. 5 is a. section through one type of valley of my roof;

Fig. 6 is an enlarged section along a. valley;

Fig. 7 is an enlarged cross section through a valley showing one method of constructing the same;

Fig. 8 is an enlarged cross section of a ridge showing one method of construction;

Fig. 9 is asection showing a modified form of roof construction, and

Fig. 10 is a top plan view of the same.

As shown in the accompanying drawings I employ rafters 10 on which a series of spaced forms 11 are secured. On the forms 11 I secure a decking 12 which is coveredover by shingles 13.

As shown in Figs. 2, 3 and 4 the forms 11 extend from the center of one rafter 10 to the center of another and are provided at their ends with rabbets 14 which fit over the rafters. The bottom edge of the forms lie 40 flush with the bottom of the rafters while the top is shown as curved rising from a low point at the center of the forms to a high oint at the center of the rafters and extendmg above the latter in a series of graceful so curves to form alternate ridges and valleys.

Each form consisting of one complete valley with a half of a ridge at each end. The deck.-

ing 12 isthen laid over the forms 11 and secured thereto by nailing.

For economy I prefer to construct the decking 12' of short lengths of lumber 15,

decking 12 and secured to the strips 15 is the shingling 13. This consists of rows of composition shingles 16 which extend from the center of one rafter to the center of the next or in other words from the center of one ridge to the center of the next. The

shingles have their bottom edges overlap ping the top edge of the preceding shingle, (see Figs. 3 and 4). Over the ridge and extending approximately one third of the distance, from the center of one ridge to the center of another I lay a row of shingles 17 overlapping one another similar to the shingles 1 The overlapping of the shingles 16 neces sitates the use of a filler shingle 18 at the lower end of the roof so that the shingles 17 may be laid without bending the same.

At the eaves of the roof I provide a finish strip 19 of the same configuration as the forms 11 and'sufliciently high to cover theends of the strips 15 and the rafters 10. This finish strip 1s preferably secured to the ends of the rafters prior to the laying of the shingles. At the gable end of the roof I provide a'rafter 20 of a greater depth than the rafters 11, andto the outer side thereof I secure half round forms 21 in line with the forms 11'. The curve of the forms 21 corresponds to the curve of the ridge portion of the forms 11 and matches the latter at their juncture. The. decking and shingling over the form 21 is the same as over the forms 11, (gee Fig. 2). At the able end of the roof t e eaves are finished 0 on the under side by securing to the under side of the protruding forms 11 a ceiling 22 preferably made of long ton ued and grooved boards. Secured to the ra er 20 and the underside of the ceiling 22 I provide other false rafters 23 laid at right angles to the rafter 20, for ornamental urposes only.

or this ty e of roof it is necessary to provide a novel orm of valley and in Figs. 5, 6 and 7 I have shown\ one form of diagonal valley involving the features of my invention, whic may be used at the juncture of the two roof portions A and B of Fig. 1. The

valley as shown, comprises tau-shaped form to a bottom member 27. Theside members consisting of side members 25 and 26 secured 25 and 26 are of such a configuration as to allow the decking 12 to join the valley without any distortion of the configuration given to it by the forms 11. This may require some hand fitting and the use of a hatchet which will leave a more or less ragged surface consequently in order to be sure of a good contact of the decking with the side members 25 and 26, I use several layers of a feltlike packing 28 known as Irish moss laid with a coat of hot tar between each layer. For the purpose of weather proofing, I apply a substantial coat of tar 29 to the entire valley and for ornamental purposes I apply a coating of crushed rock 30 over the hot tar. The crushed rock used will preferably be of the same color as the composition shingles mak ing the whole roof the same color.

In the construction of a straight valley there will be no elongation of the curves of the side members 25 and 26, they will merely be of the same configuration as the forms 11 and packed with the moss 28, and coated with tar and crushed rock the same as the diagonal valley.

In Fig. 8 I have shown one form of ridge construction which consists in securing to each side the ridge pole 32 a series of forms 33 similar to the forms 11, and provided with slots for the passage therethrough of the rafters 10. Secured to the forms 33 in the same manner as the forms 11 is the decking 12 and the shingles 13. On the top of the ridge pole 32 I provide a-member 3 1 which projects out over the shingling. Secured to the decking 12 and the chamfered edges of the member 34 is an arched crown member 35 similar in texture and color to the shingling 13. The space between the member 25 and the member 84,- is packed with hot tar and Irish moss.

In Fig. 9 I have shown a roof constructed similar to that previously described except that I. use, instead of the short forms 11, which reach only from center to center of the rafters, elongated forms 40 which span a plurality of the rafters 10 on which decking strips 15 are laid. In Figs. 9 and 10 I also show a slightly different method of applying the covering. This consists of first laying and securing to the decking 15 strips of material such as building paper 41 which extend the full length of the roof instead of only from center to center of the ridges as previously described. These strips overlap at their edge 4:2. Over these strips 41 the shingles 17 are laid in the same manner as here inbefore mentioned. The texture and color of the stri s 41 is preferably the same as the shingles ll From the foregoing description it will be seen that I have invented an improved roof which is highly efficient, ornamental and may be economically manufactured.

What I claim is:

1. A roof construction comprising a plurality of substantially parallel rafters extending upwardly from the eaves, a plurality of form members arranged on said rafters and extending at substantially right angles to said rafters, said form members having a part fitted over the top and a part extending downward and parallel to the sides of said rafters, the upper surface of said form members be ing corrugated to form valleys and ridges, decking strips arranged on the form members and transverse thereto in close parallel relation, said decking strips extending substantially parallel to said rafters, and a flexible waterproof member arranged on said decking strips.

2. A roof construction comprising a plurality of substantially parallel rafters extending upwardly from the eaves, a plurality of form members arranged on said rafters and extending at substantially right angles to said rafters, said form members being recessed to fit over the top and the sides of said rafters and the upper surface of said form members being corrugated with the valleys of the corrugations disposed between the rafters and with the ridges of the corrugations surmounting the rafters, decking strips arranged on the form members in close parallel relation, said decking strips extending substantially parallel to said rafters and a flexible nonmetallic waterproof member arranged on said decking strips.

In testimony whereof, I hereunto aflix my signature.
